One interesting fanfiction with this concept might be 'The Forgotten Dean' on FanFiction.net. It explores how the other characters react to Dean with no memories and how he slowly tries to piece his life back together. It has some great character development and emotional moments.
I've heard of a really unique take on this in a fanfic where Dean gets his memories wiped and ends up in a completely different world. He has to adapt and figure out who he is without his memories. The author does a great job of creating a new and exciting setting for Dean to navigate through his memory - less state.
One common plot device is the search for a cure. Sam or other characters will go to great lengths to find a way to restore Dean's memories. This often leads to a lot of research and exploration of different supernatural elements in the 'Supernatural' universe.
I've read a fanfic where Dean's half - human nature led to some really interesting plot twists. In this story, he had to learn to control new powers that came with his changed state. It was exciting to see how the author incorporated the Supernatural lore into this new concept of Dean. It's called 'Half - Human Dean: New Abilities'.
It could be about fan - created fictional stories where the character named Dean is involved in some rather unconventional or 'kinky' situations in the context of fanfiction. However, without reading the specific fanfiction, it's hard to say exactly what those situations are.
In the 'odin gets wiped fanfiction', it might be that Odin has his powers wiped instead. This would change the power dynamics in the story. He would no longer be the all - powerful figure. His allies may have to step up and protect him, and his enemies might see this as an opportunity to attack. It could also be a chance for Odin to grow in a different way, learning to rely on other skills or relationships rather than just his godly powers.
One great fanfiction could be 'Buffy and Dean's Unexpected Journey'. It explores how they deal with the pregnancy in a world full of supernatural threats. It's really interesting as it combines the two different universes they come from and shows how they support each other during this challenging time.
A lesser - known but really good one is 'Dean Winchester's Kidnap Nightmare'. Here, the kidnapping is part of a bigger plot by an old enemy. The fanfic has a lot of action as Dean tries to fight back against his captors while waiting for Sam to rescue him. The dialogue in this story is quite engaging.
Well, it could mean that Dean is exploring different interpretations of his relationship with Castiel. Maybe he's curious about how fans see their dynamic.
You can try searching on some popular fanfiction websites like Archive of Our Own (AO3). It has a vast collection of fanfictions across various fandoms, so there's a chance you might find the 'dean gets kinky fanfiction' there if it exists.
Another possibility is Heimdall. As the all - seeing guardian of the Bifrost, he would be aware of Odin's situation from the start. He could be the one trying to piece together what happened to Odin and prevent any disasters that might occur as a result of Odin's wipe. His unique abilities and loyalty to Asgard would make him a strong candidate for the main character.
Dean would probably be extremely confused at first. He might stand there, staring at his car with a bewildered look on his face, muttering things like 'This can't be real'.
